When setting up a paper folding type animation ( origami-like)
is there an easy way to rotate a primitive or group of points exactly
around a selected edge??
This would obviously need to be done many times in an origami type
animation, but a basic example
would be
1) 3x3 poly grid
2) then divide to get 8 triangular shaped polys
3) then be able to grab one of the corner poly and rotate it exactly
around it''s inside edge, just like a fold.
Seems like there should be a straight forward way to do this but I'm
missing it.
